Hello Stephen,

I will respin the original patch (https://patchwork.kernel.org/patch/10698089/)
once more to accommodate new feedbacks from Lubomir Rintel. This patch fixes the
build problem related to tools/perf. As Lubomir suggested, it might be better to
split the tools/perf changes ("tools: Replace open encodings for NUMA_NO_NODE")
from the original patch and then fold this fix onto it with both signed-off-by.
Does it sound good. Are you okay with it ?
